Millie Bobby Brown's Hidden Tattoos Seen at 'Enola Holmes 2' Premiere

Millie Bobby Brown was pretty in pink while showing off her rarely-seen tattoos. The 18-year-old actress hit the red carpet on Thursday in New York City for the "Enola Holmes 2" premiere in a backless light pink Louis Vuitton gown. The "Stranger Things" star's gorgeous custom dress allowed her to show off her growing tat collection, which is four little ones as of right now. Two of them are nods to very important parts of Millie's life: her "Stranger Things" character and her grandmother.
